For several years Brooks, an archeologist at George Washington University, had been pursuing the heretical hypothesis that humans in Africa had invented sophisticated technologies even earlier, while their European counterparts were still getting by with the same sorts of tools they’d been using for hundreds of thousands of years.If conclusive evidence hadn’t turned up, it was only because nobody had really bothered to look for it.The fossilized remains of extinct animals found near the object also provide a biostratigraphic record that can offer clues to a new find’s relative age.(If a stone tool is found alongside an extinct species of horse, then it’s a fair bet the tool was made while that kind of horse was still running around.)

When an organism dies, it contains about the same ratio of carbon 12 to carbon 14 that exists in the atmosphere.A few feet away, the scientists uncovered pieces of an equally well crafted daggerlike tool.
